Aircrafts spend a very large amount of their time on the terminal of the airport and the passengers require some services while they are waiting for their flight to take off. The services provided while the passengers wait are called Aircraft GSE. These services are either provided independently by the airline or they are provided through contracts with other airlines to avoid spending too much money on setting up a whole maintenance company for the airline. The ground support equipment includes everything from basic necessities to full on luxuries such as water, electricity, magazines, pillows, blankets etc. An aircraft is many times judged by its services and ground support equipment.
